Shape Of Interference Fringes In Ydse

The shape of the interference fringes in Young’s double slit experiment when D (distance between slit and screen) is very large as compared to fringe width is nearly

In Fresnel's bipriam, the shape of interference fringes formed will be

A Young's double slit experiment uses a monochromatic source. The shape of the interference fringes formed on a screen is

If the yellow light is replaced by the violet light then the interference fringes -

A beam of light consisting of two wavelength 800 nm and 600 nm is used to obtain the interference fringes in YDSE on a screen held 1.4 m away. If the two slits are separated by 0.28 mm , calculate the least distance from thecentral bright maximum, where the bright fringes of the two waveength coincide.

In the set up shown in Fig. will you observe interference fringes on the screen ?

In order to avoid overlapping of interference frings and their obliteration (destruction) the slit width must be
